HTML Radio Button — let users pick one option (live demo)
A radio button is an <input type="radio"> that lets a user pick exactly one option from a group. Radio buttons are linked into a group by sharing the same name= attribute; only the selected option's value is submitted. Below is a working form with a radio group that actually submits.

The HTML Radio Button example below is a complete, working form — paste it into any HTML page and it submits, no edits to the markup required.
No backend to build
Your html radio button form posts to one endpoint. No server, PHP, or API route — submissions land in your inbox and a searchable dashboard.
A form that really submits
Unlike a static reference snippet, this <input type="radio"> form actually sends data to a free splitforms backend, with spam filtering built in.

The <input type="radio"> element
Which HTML Radio Button attributes matter?
The <input type="radio"> element takes a handful of attributes — these decide how your form behaves and what actually gets emailed to your inbox when someone submits.
- name — The group key. Radios that share a name= form a single group — selecting one deselects the others.
- value — What gets submitted for the group when this option is chosen. Without it, the browser sends "on".
- checked — Boolean. Pre-selects an option when the page loads.
- required — Boolean. Put it on at least one radio in the group to force a selection before submit.
- disabled — Greys out the option and excludes it from submission.
- id — Used to pair a <label for> with this specific radio. The group identity comes from name=, not id.
Common mistakes
HTML Radio Button not working? Here's why.
Most broken forms come down to a few small mistakes with the <input type="radio"> element. Check these before you ship — then forward every submission to Slack or a webhook.
- Same name = same group — Radios only behave as a group when they share a name=. Two radios with different names are independent and can both be selected.
- Always set a value — Without value=, a selected radio submits the literal string "on". Set a meaningful value on every option so you can tell them apart.
- Once selected, you can't un-toggle — Clicking a chosen radio again does not clear it. Provide an explicit "None" option if the field should be optional.

40 quotes on record — from indie hacks to agency migrations.
“I replaced a Lambda + DynamoDB + SES contact form with six lines of HTML. It took eleven minutes, and the dashboard is better than what I was going to build.”
“We migrated 14 client sites off Formspree in a single weekend. The price is a third of what we paid, the API is more honest, and the spam filter actually works.”
“The webhook payload is signed, idempotent, and well-shaped. It reads like code from a competent team, not a CRUD app held together with duct tape.”
“I stopped reaching for Typeform on small marketing sites. splitforms covers 90% of the use case at none of the bloat.”
“I onboarded our whole agency in an afternoon. The MCP integration meant Cursor literally dropped the form straight into our client repos for us.”
“The free plan gave me 500 submissions before I paid a cent, and Pro is five dollars a month. I've spent more on coffee deciding which backend to use.”
“Spam went from forty junk entries a day to zero, with no reCAPTCHA puzzle ruining the form. The honeypot and time-trap just quietly do their job.”
“Point the form action at one endpoint and you're done. No SDK, no client library, no build step. This is how a form backend should feel.”
“Leads land in Slack the second someone submits, and a copy goes to Google Sheets for the sales team. I wired both up in under ten minutes.”
“I run a static Hugo site on a five-dollar VPS. splitforms gave it a real contact form without me standing up a single server.”
Questions
HTML Radio Button questions, answered.
View all FAQsWhat is a radio button in HTML?
A radio button is an <input type="radio"> control. Radios that share the same name= attribute form a group, and the user can select exactly one option from that group. The selected option's value is submitted with the form.
How do I let users select only one radio button?
Give every radio in the set the same name= attribute. The browser then allows only one to be selected at a time — selecting one automatically deselects the others in the group.
How do I create a radio button group in HTML?
Use multiple <input type="radio"> elements with the same name= but different value= attributes, each wrapped in a <label>. Place them inside a <fieldset> with a <legend> for an accessible group caption.
How do I set a default selected radio button?
Add the checked attribute to the option you want pre-selected, e.g. <input type="radio" name="plan" value="pro" checked>.
What value does a radio button submit?
It submits the value of its value= attribute. If you omit value=, the browser submits the string "on", which is rarely useful — always set an explicit value on each radio.
